This Technical Specification specifies a method for the determination of the size distribution of particulate
biofuels by the oscillating screen method. The method described is meant for particulate biofuels only, namely
materials that either have been reduced in size, such as most wood fuels, or are physically in a particulate
form. This document applies to particulate fuels with a nominal top size less than 3,15 mm (e.g. sawdust).
